5. SITE SELECTION
5.1 Consider the following when selecting an existing pad or platform for enclosure
placement:
•
•
The enclosure may be installed on a new or existing concrete pad or metal
platform. Obtain rights-of-way and other permits (building permit, electrical
permit, etc.), depending on local codes and authorities, prior to installing the
enclosure.
The mounting pad or platform must be installed (according to local practices)
before the enclosure can be installed.
5.2 Consider the following when deciding on the location for the rooftop site:
•
•
•
Obtain all necessary building permits and other local approvals as necessary
per local building codes.
Select locations that will provide enough space to place the mounting platform
and enclosure, and provide safe working conditions.
Select locations where there are no electrical lines that could touch the
enclosure and energize it.
5.3 Consider the following when deciding on the location for the concrete pad or platform:
•
•
•
•
•
Place the enclosure on servitudes, on dedicated (recorded) easements, or on
property owned by the company. Avoid any unrecorded easements.
Use public safety road and street rights of way only where there is enough
space to place the enclosure and provide safe working conditions. The
enclosure should be easily accessible with adequate parking to ensure safety
for people and vehicles. Place the enclosure where it will not create a visual or
physical obstruction to either vehicles or pedestrians.
Select locations that will minimize accidental or intentional vandalism.
Consider the use of protective posts when the enclosure is located near parking
areas where vehicles could back into it. Do not place the enclosure in ditches
or areas subject to flooding. Do not place the enclosure in an area where the
pad is subject to vehicle loads.
Place the enclosure at least 42 inches (106.68 cm) away from any obstruction,
fence, hedge, etc. Include adequate area for craft personnel to perform
maintenance procedures.
If an area is subject to frost, choose a site free of heaving.
ALERT
All enclosure grounding and ground ring must be installed prior to turn up of
enclosure.

7.4 Referring to Fig. 20, prepare a form per the following steps. Follow local practices or
building codes if different than the information included in this section:
Step 1: If the soil is not firm, compact it per local practices. For a typical
installation, excavate the foundation hole to a depth of 12 to 15 inches
(30.48 to 38.1 cm).
Step 2: Construct a level base for the pad, using a minimum of 6 inches (15.24
cm) of sand or gravel. The pad should be level to within 1/4-inch (6.35
mm) over the entire length and width.
Note: Square and level the template(s) on the stakes so the tops of
the mounting plates are flush with, or no more than 0.25"
(1/4-in). (6 mm) above, the top of the pad. Square the
template(s) so the diagonal measurement between the
anchor bolts is equal.

11.1 Safety Precautions
DANGER
Risk of Electrical Shock, General
•
•
•
All ground connections must be installed and verified, prior to connecting any
power cables (AC or DC) and turning-up of enclosure.
Before installation, the AC grounding electrode system must be bonded to an
AC main service power neutral/ground bus. Contact your local power company
or local practices for information about codes or restrictions for your
installation.
When connecting any discrete power connection, make the connection first
with the ground/return and break last with ground/return.
DANGER
Risk of Electrical Shock, AC
•
•
•
•
•
Proper actions, include, but not limited to:
Verify before contacting the enclosure that no current leakage or ground fault
condition is present.
Verify a proper ground is in place.
Verify for AC hook-up, all enclosure circuit breakers are OFF and the utility
incoming feed is OFF.
Use a trained licensed electrician.
DANGER
Electrical Hazard
Observe all safety precautions as specified by local building codes and the
National Electrical Code (NEC). All procedures should be performed by a
licensed electrician. If local building codes specify procedures different from
those in this section, follow local codes.

11.2 Enclosure AC Schematic
The complete system schematics are included with each enclosure.
11.3 Grounding the Enclosure
ALERT
Grounding should be accomplished according to local practices and in accordance
with the latest NEC codes.
All enclosure grounding and ground ring must be installed prior to turn up of
enclosure.
The enclosure should be grounded to an external ground ring using a #2 AWG
solid wire. The resistance of the ground ring, as verified with a Megger, shall be
less than 25 ohms.
Enclosures without side chambers are equipped with a ground bar located at the
rear of the enclosure. Enclosures with one side chamber are equipped with a
ground bar located in the side chamber. Enclosures with two side chambers are
equipped with a ground bar located in each side chamber. Enclosures with one
ground bar (enclosures with no side chamber or one side chamber), the ground bar
can be designated as the enclosure’s Main Ground Bar (MGB) (depending on local
practices). Enclosures with two side chambers, one ground bar must be designated
by the customer as the MGB.
The internal frame and external enclosure are factory grounded to a ground bar
located inside the enclosure.

12. INSTALLING AND CONNECTING BATTERIES
12.1 Safety Precautions
DANGER
ELECTRICAL HAZARD. Risk of serious injury and/or equipment damage.
•
•
•
Exercise extreme care when handling the batteries and connecting them to the
string. Two people are recommended for lifting and placing batteries. Wear
heavy gloves and safety glasses while lifting the batteries. Handle each
battery ONLY by its lifting slot. Keep hands well away from the connector
posts.
Arcing is possible during battery connection procedures. Use heavy gloves
during all procedures involving the batteries to avoid potential injury. Do not
wear rings, metallic wrist bands or bracelets when working on batteries. Do
not allow metal objects to rest on the batteries or to fall across the terminals.
Make sure the battery disconnect breakers are set to “OFF”.
DANGER
Electrical and Explosion Hazard.
Batteries can be a lethal source of electrical power under certain conditions.
Batteries are electrically live at all times. Although the voltages are not
hazardous, the batteries can deliver large amounts of current. Even if the case is
damaged, the battery is capable of supplying high short-circuit current.
12.2 General
NetXtend™ Flex Dual Bay configuration options allow batteries to be housed in
an external battery base, which can accommodate either -48Vdc or +24Vdc battery
strings.
Before installing the batteries, refer to:
•
•
•
The schematic drawings shipped with your enclosure for a wiring diagram.
The battery vendor’s documentation set for installation and testing
instructions.
Battery vendors documentation set for battery safety precautions and notices.
A battery disconnect circuit breaker is provided in the Equipment Compartment
for each string of battery the enclosure accommodates.

12.3 Installing Batteries
Depending on enclosure configuration, 12Vdc 155 Ah (minimum) front post
batteries are installed in an external battery base.
Note: The enclosure is not shipped with batteries installed. The batteries
are to be installed in the field.
Perform the following steps in installing the batteries:
Step 1: Open the enclosure’s front door and secure the wind latch.
Step 2: Refer to the appropriate views in Fig. 46, Fig. 47, or Fig. 48, and remove
any front cover, braces, and battery retaining brackets as required. Set
these and the hardware aside for re-use.
Step 3: Ensure all battery disconnect circuit breakers are in the "OFF" position.
Step 4: Using a Digital Multimeter (DMM), measure the battery voltages to
make sure all batteries are in good condition. A good battery will
indicate approximately 12.5Vdc.
Step 5: If necessary, remove all the connecting hardware from the battery
terminals.
Step 6: Coat all battery terminals with an anti-oxidation compound
(NO-OX-ID-A).

14. CLIMATE CONTROL OPTIONS
The NetXtend™ Flex dual bay outdoor enclosures can be configured with several
climate control options, as described in this section.
Note: Climate control units can be mounted on each door of the enclosure.
See Fig. 55 on page 76 for typical installation of multiple climate
control units.
14.1 Heat Exchangers
Refer to this section when the NetXtend™ Flex dual bay outdoor enclosure is
equipped with a heat exchanger. The heat exchanger is a vertical air flow device
that will keep the equipment or batteries within the manufacturer's
recommended temperature range. The exterior cooling air is never mixed with the
air in the electronics chamber. The NetXtend™ Flex heat exchangers are door
mounted and offered in three standard sizes. 1000W, 1450W and 2800W (see
Fig. 52).
The heat exchangers are equipped with internal and external fans that can run
independently of one another. If one fan fails, the others will keep operating. The
external fans draw exterior air through the bottom of the enclosure and exhaust
it out into the air chamber in the enclosure top. The internal fans draw interior
air in from the top of the equipment chamber and exhaust it out the bottom of the
chamber. See Fig. 54 for a heat exchanger air flow diagram.
As part of the installation process, a quick check of heat exchanger operation can
be performed by the following:
Step 1: Confirm fan operation by noting sound and air movement near the vents
on the door.
Step 2: If fans do not operate as expected when the enclosure is first installed,
press the reset button on the ECU (Fig. 56 or Fig. 57). If the problem is
not resolved after resetting the ECU, contact Emerson Network Power
technical support at (800) 800-5260.
Step 3: If replacing a heat exchanger fan refer to Section 15.1, Heat Exchanger
Fan Replacement on page 93.

14.1.2 Heat Exchangers - Environmental Control Unit (ECU)
The ECU controls the heat exchanger’s thermal components. Besides controlling
the thermal components, the ECU also provides the following functions:
•
•
•
monitoring for thermal system component failure (fans and thermistors),
high and low temperature alarming,
and intrusion alarming (audible and extended relay contacts).
Refer to Fig. 56, Fig. 57 and Fig. 58 for illustrations of an ECU controlling a heat
exchanger.
All thermal system components are input voltage and polarity sensitive. These
instructions cover both +24Vdc and -48Vdc systems. Refer to the label on the front
of your ECU for the specific voltage requirement of your ECU.
ECU Input Voltage Range:
•
•
+24Vdc ECU: +20.0Vdc to +28.3Vdc.
-48Vdc ECU: -40.0Vdc to -56.7Vdc.
ALERT
The ECU requires either +24Vdc or -48Vdc input voltage, depending upon enclosure configuration. Observe proper polarity for ECU input connections to avoid
equipment damage. Polarity for the two input voltages is as follows:
+24Vdc Input Systems: 24V Battery is +, 24V Return is -.
-48Vdc Input Systems: 48V Battery is -, 48V Return is +.
14.1.3 Heat Exchanger Thermal Components
The heat exchanger thermal components controlled by the ECU consists of:
•
•
•
1000W Heat Exchanger - 6 fans (3 internal loop / 3 external loop)
1450W Heat Exchanger - 8 fans (4 internal loop / 4 external loop)
2800W Heat Exchanger - 4 fans (2 internal loop / 2 external loop)
All heat exchangers also include (2) enclosure thermistors. See next section for
further detail.
Note: APC (Acoustic Pleasing Code) fan codes are used. Fan RPM's are
limited to approximately 1/3 fan speed up until approximately 60°C
internal temperature. This is done to optimize the enclosure acoustic
performance (i.e., keep the enclosure quiet), while maximizing the
heat exchanger performance. The fan speeds are dictated strictly by
reading the enclosure's internal temperature via the two supplied
thermal sensors.

be housed in the enclosure is -40°C to +65°C. The purpose of the heat exchanger is
to remove heat dissipated from equipment while maintaining equipment inlet air
temperature. By controlling enclosure air temperature, the ECU maximizes
electronic equipment life. In addition, the ECU limits acoustic noise by reducing
fan speeds when possible.
Refer to Table H and Fig. I for ‘Heat Exchanger Temperature and Alarm States’.

Enclosure Temperature Sensors
The ECU has two thermistors for sensing air temperature. Both are located inside
the enclosure and determine the Enclosure Air Temperature (Tenclosure).
(Tenclosure is defined as the highest temperature measured of the two enclosure air
sensors.)
The enclosure air thermistors are factory placed as follows:
•
•
Enclosure Air 1 Thermistor is located at the heat exchanger return vent.
Enclosure Air 2 Thermistor is located on the rack at the highest point in the
enclosure. The placement of this thermistor is flexible and may be relocated by
the customer to the intake of a critical piece of equipment. Remember, the
ECU bases cooling on the hotter of the two enclosure air sensors.
Fan Speed Control Scheme
See Fig. 59 and Fig. 60 for Fan Speed vs. Internal Temperature charts.
•
•
Fan speed is determined by the enclosure air temperature readings.
The speed of internal loop fans is controlled separately from the speed of
external loop fans.

Once a bank of fans has turned "on", all fans in the bank run.
Once either bank of fans turns "on", the other fan bank also turns on to
maximize cooling.
If the temperature reaches 40°C (104°F) inside the enclosure at either internal
thermistor, ALL FANS RUN.
Typically, all fans will be OFF if the internal temperature falls to 35°C (95°F).
The ECU varies the speed of the fans between OFF and Maximum Fan Speed
for the various ranges to maintain Tenclosure at the Set Point Temperature.
All fans will slow and eventually shutoff for any enclosure temperature less
than the Set Point Temperature (see above).
High Temperature Override: If Tenclosure exceeds 67°C at any time, the
ECU overrides the Maximum Internal and External Fan speed limits and runs
all fans at maximum speed. Fans return to normal speed control when
Tenclosure is reduced to 60°C.
Minimum Run Time: To prevent rapid cycling of the fans, the ECU has a
minimum run time and a minimum off time for fans. Once fans are turned on,
they run for a minimum of 5 minutes. Once fans are turned off, they remain
off for a minimum of 5 minutes.
Exception to Minimum Run Time: If Tenclosure goes above Set Point +5°C,
the minimum off time is overridden, to prevent enclosure air temperature from
exceeding the maximum operating limit of the equipment. If Tenclosure goes
below the Set Point -5°C, the minimum run time is overridden, to prevent
enclosure air temperature from falling excessively low in temperature.
Fault Conditions: Refer to the next section titled "Failure Modes".
14.1.5 Failure Modes
In general, the application accounts for single points of failure. Failures will cause
the enclosure to enter a system fault mode in which cooling device is turned full
on. Refer to Table J for a Fault Condition Summary.

14.1.6 ECU User Interface (+24VDC and -48VDC ECUs)
Initial Start-Up Sequence
When power is first applied to the ECU, the ECU goes through the following
Start-Up sequence.
Start-Up Sequence
1. Firmware revision number displays. The ECU displays "FC" followed by a
3-digit number. Applicable code in this practice is Version "2.0.0" or later.
2. 1000W and 1450W HX: All fans run at full speed for 30-45 seconds to detect
any fault conditions, then fan speeds will decrease gradually to the normal
operation mode based upon the sensing thermistors, per code operation
curves.
Note: If either enclosure door is open during turn-up, the alarm buzzer
sounds and a d01 door open alarm appears on the front ECU display.
To silence the buzzer and clear the d01 alarm for 30 minutes,
momentarily depress the Audible Alarm Cutoff / Maintenance / Reset
pushbutton located on the ECU (see Fig. 56). This also inhibits the
remote intrusion alarm from being sent and turns all fans and
components "OFF" for 30 minutes.
3. "UP" displays (if everything is operating as expected and there were no
problems found with any component).
or
Continuous cycle of error codes if any faults detected.
4. When a call for cooling occurs, the code requires the cooling fans to run a
minimum of 5 minutes. Unless temperatures fall to 29°C, the code will shut
down the fans (so no thermal shock occurs to the equipment).
